The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity, and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you mig...

The long-lived Mars rover Opportunity has spotted bright veins of a water-deposited mineral, apparently gypsum, on the surface of the planet. The vein is informally named 'Homestake,' and it and other similar-looking deposits are located in a zone wh...

Many of the coolest DIY projects we feature require a special electronics board called an Arduino, and if you've been putting off learning how it works, now's the time to learn—this step-by-step comic makes it super easy.

We have a lot of love for microdrones here at PopSci--everything from bird-like flapping wing drones to cyborg insects controlled by microcomputers--so we're thrilled to see the Air Force is showing them some love as well. The Air Force Research Lab ...

Also contained in rocks once molten are radioactive elements whose isotopes provide Earth with an
atomic clock. Within these rocks, "parent" isotopes decay at a predictable rate to form "daughter"
isotopes. By determining the relative amounts of pa...

As can be seen in
,
the three
of any triangle always pass through its incenter.
In this construction, we only use two, as this is sufficient to define the point where they
.
We bisect the two angles using the method described in
. The point ...

According to Alfréd Rény and/or Paul Erdos, "A mathematician is a device for turning coffee into theorems." But while being able to pee theorems is way cooler than writing your name in the snow, according to movies, math will drive you insane:
